What it is and what it does

BPC-157 arginate, often called “pentadeca arginate” or PDA, is BPC-157 formulated as an arginine salt rather than an acetate salt. It is at the same early stage of research as BPC-157, with no independent data on this form yet. It is commonly discussed as a more stable, more bioavailable version.
